What is the EPA stream water quality rate for fecal coliforms?

The correct answer highlights that the EPA’s standard for stream water quality regarding fecal coliform bacteria is established for assessing water safety, particularly in recreational waters and sources of drinking water. The value of 2 colonies/1 ml is significant as it is a threshold used by environmental and health agencies to identify water safety levels.

At this colony count, higher levels of fecal coliforms indicate potential contamination by fecal material from warm-blooded animals, which could pose health risks to humans through exposure or ingestion. This standard is critical for maintaining public health and protecting aquatic environments by ensuring that the water quality is monitored and managed effectively.
